F inishing Grinding, polishing and de-burring machinery

LOESER is a leader in technology required to produce high quality surface finishes, working closely with major abrasive belt manufacturers. From simple one-station machines to completely automated multiple- station systems, Loeser custom engineers systems to each customer’s exact needs. New Loeser pressure controlled grinding technology allows for heavy stock removal, tolerance grinding and fine finishing. Abrasive belts can be changed very quickly when worn out, offering a major time advantage compared to stone grinding or turning. Loeser machines can be equipped with multiple stations in different combinations, completely enclosed or open style. Systems are fully modular and easy to upgrade with additional stations ML100 3Z from NS Máquinas Industriais is a round pipe polishing machine with three independent abrasive stations. It finishes tubes from Ø10 to 114mm in one single pass, using a combination of different abrasive grains. The machine is suitable for stainless steel tube finishing where high quality is required, and can also polish oval shapes. Using the ML planetary system, the abrasive belts rotate around the tube giving a flexible finishing without spinning the tube. This enables the safe work of long tubes and also of drilled tubes.

to grow with future requirements. For mirror polishing of stainless tube, Loeser produces a combined machine consisting of wet pre-grinding module and centreless cotton wheel buffing using a polishing compound. For extremely high stock removal applications, Loeser offers high speed abrasive belt grinding instead of turning, with the machine types RPS376 and RPS377. The company’s centreless grinding and microfinishing RPS+SF model is suitable for the finishing of pistons, bars and axles with high frequency microfinish to reach super fine finish up to 0.004µm Ra. For super high quality chrome stripping and finishing of gravure cylinders, Loeser NS has developed a new in feed and out feed system that provides continuous transport of tubes, avoiding labour costs and reducing non-productive periods. The new system is able to feed and polish, in the same sequence, tubes with different lengths, working from a minimum tube length of 450mm. As the feeding is performed from the front of the tube, unlimited lengths can be worked. The standard capacity is designed for ten tubes, but higher numbers can be processed with different versions of the loading and unloading tube system.

offers model HSD+SF. Loeser’s product line has recently been expanded to include complete continuous through feed chrome plating systems. This new addition combined with continuous through feed induction hardening systems means that Loeser is able to offer solutions for: through feed induction hardening; through feed belt grinding pre chrome; through feed continuous chrome plating; through feed polishing post chrome; and through feed application of special wax for added corrosion resistance.

ML100 3Z also includes a new energy- saving feature: it is equipped with a tube detection program that automatically stops the abrasive belts’ motors whenever there is no tube on the finishing stations. This automatic start and stop system reduces not only the consumption of energy, but also of bearings, rollers, V-belts and other mechanical components. The automatic tube feeding system is also compatible with double and single station tube finishing machines in dry or wet versions.
